var urlbar = document.getElementById("urlbar");
 urlbar.setAttribute("autocompletepopup", "PopupAutoComplete");

Hi, I just discovered userChrome.css the other day after upgrading to firefox 9.0.1. I was previously using some no-longer-working extensions, and have transitioned most of what I was getting from those to userChrome.css. There is one remaining extension I am using, oldbar, which is a nearly trivial bit of javascript: function oldbarStartup(event) { var urlbar = document.getElementById("urlbar"); urlbar.setAttribute("autocompletepopup", "PopupAutoComplete"); } window.addEventListener("load", oldbarStartup, false); I was wondering if this can also be accomplished in userChrome.css? I have tried a few variations on #urlbar { autocompletepopup: "PopupAutoComplete" !important; } with no success. thanks for any help, Greg
